• Test backend business logic supporting study, series, and image metadata management 

• Validate database operations, schema changes, relational integrity, and backend data consistency across SQL Server, Postgres, and related storage systems 

• Test authentication and authorization flows including role-based access, JWT authentication, and identity systems 

• Evaluate system performance, scalability, concurrency behavior, and reliability under high-volume imaging workloads 

• Test cloud-hosted services, containerized applications, and distributed microservice interactions (AWS preferred) 

• Build and maintain test harnesses, mocks, utilities, and automation tools supporting backend and distributed system testing 

• Analyze backend logs, API traces, service interactions, and monitoring data to isolate defects and support troubleshooting 

• Validate logging, audit trails, monitoring behavior, and observability mechanisms in regulated healthcare environments 

• Integrate automated tests into CI/CD pipelines and monitor automated quality gates 

• Investigate, document, and track defects; verify fixes and perform regression testing across the full application stack 

• Validate deployments, perform smoke testing, and support production issue investigation 

• Ensure testing practices align with healthcare security, privacy, compliance, and data protection requirements 

• Collaborate closely with software developers, architects, and DevOps teams to improve product quality and testability 

Required Qualifications  

• 7+ years of professional experience in software QA, test automation, software development, or Software Development Engineer in Test (SDET) roles  

• Strong development or automation background may compensate for years of experience 

• Strong scripting and automation skills using Python, PowerShell, JavaScript, or similar languages 

• Solid understanding of C#/.NET and modern backend development principles 

• Experience testing RESTful APIs, backend services, distributed systems, and asynchronous workflows 

• Hands-on experience validating real-time communication systems such as SignalR or equivalent technologies 

• Strong understanding of concurrency, asynchronous processing, and race condition validation 

• Familiarity with SQL Server, Postgres, relational data modeling, and backend data validation 

• Experience testing cloud-hosted applications, microservices, or distributed systems (AWS preferred) 

• Understanding of secure application development and testing practices 

• Experience with Git and modern team-based development workflows

• Experience with AWS-based healthcare systems or cloud-native architectures 

• Experience in medical imaging or healthcare applications 

• Familiarity with DICOM concepts including Study, Series, and SOP Instances 

• Experience validating integrations with PACS or imaging storage systems 

Desired Attributes  

• Strong attention to reliability, scalability, workflow correctness, and data integrity 

• Ability to validate complex distributed systems and compliance-sensitive applications 

• Strong technical mindset with software development and automation-oriented thinking 

• Ability to troubleshoot across UI, backend services, databases, cloud systems, and distributed workflows
